Beschreibung
Zusammenfassung:	The present invention provides a conjugated diene-based polymer excellent in processability in vulcanization, and excellent in abrasion resistance and a low hysteresis loss property of a vulcanizate obtained therefrom. The present invention relates to a conjugated diene-based polymer, having a branch number measured by viscosity detector-equipped GPC-light scattering measurement of 7 or more, an amount of bound aromatic vinyl of 1% by mass or more and 32% by mass or less, and a content of vinyl bond in bound conjugated diene of 11% by mol or more and 35% by mol or less.
